is now admitted into the upper compart.

ment so that the .milk is forced into the lower compartment to admix with the bran.

This invention hasfor its object to im prove apparatus of this kind insuch a mannor that it is no lon r necessary to enclose the vessel in a w on box for heating the milk, as the wall of the vessel is reinforced and a very hi h steam pressure is made to act upon the ran so that the inner structure of the bran is torn and the bran becomes so rous that it more readily absorbs the mil vaccinated with bacteria.

The im roved apparatus is shown by way of examp e on the accompanying drawing,

Fig. 1 in side elevation, partly section and m v between the two mechanism a, a"

A vacuum pipe h having a cock iis connected with the vessel b. A pipe 70 for supplying steam under pressure isconnected wlth'vesv sel b at the side 0 posite the vacuum pipe h.

Into the cups aped vessel b about 30 liters of condensed milk and some pure culture of yolghurt bacteria are poured. The hood- 0 is lled with bran and through the pipe khigh. pressure steam is injected into the hood so that the inner structure of the bran is torn. After the .cock i has been opened a vacuum is produced in the yessel whereupon the cock 2' is. closed, the vacuum pipe h screwed ofli at nut o and the apparatus rotated 180. The cock i is opened again. The milk drops now through the wire gauze n onto the bran, the inflowin 'air exerting a pressure upon the milk. en the bran has absorbed a sufiicient quantity of milk it is remo ved from the apparatus and dried at low temperature. The product may -.be

ground to powder or compressed to form tablets.

I claim An apparatus for the production of yoghurt and similar bacteria cultures comprising in combination a cup-shaped vexel for the milk'vaccinated with yoghurt bacteria, a

hood filled with bran mounted on said cup said hood on sai vessel, a vacuum pi removably connected with said cup-s aped. vessel, a steam pipe connected with said cup-- shaped vessel for submitting the bran in the 'hood to-Vthe action of high pressure steam, and means for rotatin said ve$el180 to pour the milk onto the ran.

In testimony whereof I aflix my signature.
